Roller Rockerarms Slant 6

Those sure look nice but I'm not sure how much of a gain that they have. A couple of guys I used to race slant's with gave me mixed reviews on them. One claimed it was a gain of two tenths. The other claimed it was zero gain on his particular engine and said to save my money.

The 2 tenth gain was on the faster engine. 7.70's in the 1/8 mile. The zero gain was running in the lower 8 second range. It may just be all in the combination like most things.

There essentially IS no "gain" just like any other roller rocker arm. If you read post #17, you see where I mentioned "about" their only benefit. But, that's a big benefit, IMO. Valve guides and stems that virtually last forever. There have been many dyno experiments that show the benefits in power from roller rockers is either very little or even non existent in some cases, so if you're looking for extra power "that ain't it".
